IMPROVEMENT IN BARREL-BUNGS.

Speccation forming part of Letters Patent N o. 167,419, dated September 7, 1875; application led July 23, 1875.

To all whom t may concern.;

Be it known that I, WiLLIAM E. WHITE, of Birmingham, in New Haven county, in the State of Connecticut, have invented a new and Improved Bung for Barrels, of which the following is a specification:

Figure l is a vertical central section of my improved bung. Fig. 2 is a bottom view of the same.

Similar letters of reference indicate corresponding parts in both gures.

The object of this invention is to produce a permanent bung for barrels, and one which can be readily removed and replaced. The invention consists in the construction and combination of an annular bung with an annular bush, central screw, and inner crossbar, all substantially as hereinafter shown and described.

The letter A in the drawing represents an annular bush, of slightly conical or cylindrical form, with smoother threaded outer circumference, and with two vertical grooves, a a, along its inner circumference, said grooves being diametrically opposite one another. B is the bung, made of metal or other material, of a size and form to fit the interior of the bush, and flanged on top to lap over the upper edge of the bush, as clearly shown in the drawing. The bung is of annular formthat is to say, it is perforated in the center for the reception of a screw, C, the said perforation being larger at the upper than at the middle part, so that the head of the screw C may be sunk into the bung, as shown. D is a crossbar, perforated in its middle, and threaded to t the screw-thread of the screw C. It has a projecting top, b, shorter than the body ofthe bar. Said top b enters a socket formed in the bottom of the bung to prevent the cross bar from turning in the bung. The length of the cross-bar D is greater than the inner diameter of the upper part of the bush, but slightly less than the dist-ance between the grooves a a, so that such cross-bar can be let down through the bush when held in line with the grooves.

For use, the bush A is first screwed or fastened intova barrel. The bung to be applied is then fitted into the bush, the cross-bar passed down through the grooves a a, and the bung then turned to 'bring the ends of the cross-bar below an inner shoulder, d, which is formed in the bush A between the grooved parts thereof, as clearly shown in the drawing. The screw C is then turned to lirmly draw the cross-bar against such shoulder d, and the bung is thereby secured and clamped in place.

For removing the bung it is only necessary to unserew -the cross-bar slightly, so as to loosen it from the shoulder d, and then the bung can be turned to bring the ends of the cross-bar in line with the grooves ct a., whereupon the bung can be raised. Thus Iproduce a durable and reliable bung, which is easily removed and replaced.

I claim as my invention,-

The combination ofthe annular grooved bush A, having the shoulder d, with the annular bung B, which is ianged to overlap the upper edge of the bush, andwith the screw C and cross-bar D, said cross-bar having the projection b, whereby it is locked to the bung, so it cannot revolve without the bung, substantially as specied.
